INCANDESCENT IGNITER FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 708,284, dated September 2, 1902.

Application filed January 18,1901. Serial No. 48,694. (No model.)

To all whom it ntay concern.-

Be it known that LOARL W. IVEISS, a citizen of the United States, residingin the borough of Manhattan, in the city of New York and State of New York, have made certain new and useful Improvements in Incandescent Igniters for Explosive-Engines, of which the following is a specification.

This invention relates to explosive engines in which a non-gaseous fuel .is employed as the basis of the explosive charge; and it has for its object to provide improved means for the simultaneous ignition of the charge at different points in the cross-section of the working cylinder or explosion-chamber.

In the accompanying drawings,in which the invention is illustrated, Figure 1 represents a side elevation of an explosive-engine provided with a plurality of igniters, a part of the engine being shown in section to more clearly disclose the construction. Fig. 2 represents across-section on the line 2 2 of Fig. 1. Fig. 3 represents a cross-section on the line 3 3 of Fig. 1, showing another form of fuel-inlet and z 5 corresponding changes in the igniters.

The working cylinder or explosion-chamber a of the engine in which the explosions occur in rear of the piston b is provided with a fuelsupply pipe 0, through which the non-gaseous fuel is delivered under pressure from a suitable pump c, and with an exhaust-port d. The head or end a of the cylinder at is provided with a plurality of separate and independent igniters g, disposed at Widely-sepa rated points on the cylinder-head. Each of said igniters may be secured to the cylinderhead by a flange h, and one of them, as shown in Fig. 2, has a lip 7,, which projects into the cylinder in position to receive and vaporize the fuel, which is injected into the cylinder as I a jet through the nozzlef of the pipe 0. As

By the provision of igniters at widely-separated points of the cylinder-head ignition takes place at a number of places simultaneously, whereby a more complete and uniform explosion is obtained than is otherwise possibis. This feature is of great importance, particularly in cases where the rate of fiamc propagation is slow, as it permits a heavy oil or a mixture of c0al-d net and a volatile liquid, either of which requires very complete combustion, to be used as-fuel. Since the igniters are entirely separate and independent of each other, one or more of them can be removed for the purpose of repair without disabling the engine or preventing its operation.

I claim as my invention- 1. In an explosive-engine, the combination of a combustion chamber or cylinder, a plurality of separate and independent igniters disposed on the cylinder-head at widely-separated points to ignite the charge at different places in the combustion-chamber simultaneously, one or more of said igniters having a projection within the cylinder, and means to inject the fuel against such projection, substantially as described.

2. In an explosive-engine, the combination of a single combustion-chamber, a fuel-supplypipe having a nozzle with a plurality of inlet-openings, a plurality of separate and independent igniters disposed on the cylinderhead at widely-separated points within said single chamber to ignite the charge at different places in said chamber simultaneously, the igniters in line with said inlet-openings being provided with lips to receive and vaporize the fuel, substantially as described.

In testimony whereof I sign this application,in the presence of two witnesses, this 16th day of January, 1901.

CARL W. IVEISS.
